A -VBe it know-n that I, WILLIAMS. Roenes, a

citizen of the United States, residing at Cleveland, in the county of-Cuyahoga and State of Ohio, have invented a new and useful Improvement in Ventilating Systems, of which the following isa specification..

This application relates to a system of ventilation which lis lparticularly adapted vfor buildingsf in which volatile liquids are employed; and it consists ina series of-blow- Apipes-s which are so positioned and directed as to create a thorough agitation of the gaseous contents .of the building near the lioor, the said contents being discharged from suitable openingsat or ,near the top of thebuilding.

vIn the accompanying drawings, Figure l is a longitudinal section through a building, taken on the line 1,1 of Fig. 2 and showing my Ventilating system in use in anail-coating plant. Fig. 2 is atransverse section through thebuilding, takenon the' line 2 2.of Fig. 3; and Fig. 3 is a plan view taken substantially on the line?, 3 of Fig. 2, the, partition through the building being removed. v

In viewvof the fact that the vaporsy of gasolene and'some other volatile liquids is heavier than air itnaturally settles to the ioor, where it mixes with the air and besidesy being oppressive and injurious tothe workmen in the room it forms a mixture which may become highly explosive. In view of this fact it becomes very desirable to install in suchplaces a ventilatingsystem which will operate to remove these vapors from all parts ofthe building and which will furnish fresh and pure air thereto. A system for accomplishing thisresult is shown in theaccompanying drawings,

which, as stated, `illustrate in connection therewith a plant' forcoating nails, in which plant the nails are placed Ain the-buckets l and are liftedthe'rein by means of cranes 2 and are then loweredl into dipping tanks or vats 3, said vats containing a volatile liquid as an ingredient of the coating solution.

i When the nails are thoriighly drenched with the solution,the buckets are elevated and the nails are deposited upon ,the upper parts ofthe evaporators or conveyers li. These evaporators are inclined, as shown in Fig. vl,

and are. also shaken back and forth, sov as to cause the nails to gravitate or slide'downwardly thereon and drop from the lower ends. While thus spread upon the evaporators or conveyers the volatile ingredients of the soluplace, as is shown in Figs. l and 3, in which there is a partition 6. AThe air 'that is thus furnished is forced upwardly through the large supply-pipe 7 to a point 8,-where the pipe divides into two branches, the branch 9 extending substantially in line with-'pipe 7 70 along the-side of the building andthe other, l0, passing transverselyacross the :room to a point near the opposite side, where it turns also and extends valong the side of the building parallel `with the pipe 9.' At-intervals 75 throughout the length of the pipe 9 there are small blowpipes 11, that arebent downwardly and inwardly, so as to direct the air that issues therefrom across the room, so that it will strike the floor toward the opposite side of 8o the building, as indicated by the arrows in Fig. 2. A similar series of blowpipes 12 are connected with the pipe 10,- 's'aid blowpipes also .extending downwardly and inwardly, so

as to direct the air that issues from them toward 8 5 l the opposite side of the fioor, the direction of said blast of air alsor being indicated in Fig. 2. While this figure shows but-one `row of arrows, it willbe understood that the air is diiIused as it emerges from the pipe,` so that the air from one of the pipes is scattered over the half of theiioor which is on the opposite side of the building therefrom. After the air strikes the floor it rises,- as indicated by the arrows, and is forced outwardly through the ventilator 13 on the top of the building. This ventilator may be of any suitable form; but it should extend the entire length of the The air for Ventilating and for dry- 60 building or at least of the entire length of the evaporating-room. As shown, the sides of the Ventilator are formed of slats 14, that are inclined to prevent the entrance of rain, y

the spaces 15 between the slats affording suieient room for the gases to pass out. To more eiiiectually shut out the rain, the edges of the slats are bent vertically, as shown in Fig. 2.

In order to more effectually cover the iioorspace ofthe building and to prevent the blast from pipes 11 interfering with those from the pipes 12, I have placed the pipes in alternate arrangement, those on one side being opposite the spaces between the pipes on the other side. rlhe blasts of air for evaporating the coating solution on the nails is furnished by the pipes 9 and 10, the pipe 9 being carried across the'end of the room and terminating over the evaporator 4, as shown in Fig. 3.

The lend of the pipe is bent downwardly toward the evaporator, as shown at 16, and it is so positioned and shaped as to cause the air issuing therefrom to cover as nearly as possible the entire surface of the evaporator. A similar pipe 17 is directed downwardly from the pipe 10, `so as to furnish a blast for evaporating the nails on the other evaporator 4.

The blower 5 is driven by means of the motor 18, that is connected by suitable gearing therewith. The capacity of the blower is so proportioned with that of the building that the latter is quickly emptied of all of its air and vapors, said air being entirely changed within a space of a Very few minutes; otherwise the vapors will accumulate and the air will become charged with them to the dangerpoint.

While I claim my invention as especially adapted for use in buildings where volatile liquids are employed, I do not wish it to be understood that I deem it limited entirely to such uses, as it is evidently adapted for more general use. The nail-coating plant is herein shown and described for the purpose of a clearer description and as showing some plant to which my invention is especially adapted.

Having thus described my invention, what I claim as new, and'desire to secure by Letters Patent, is-
